2315 was, admittedly, me trying to pick something very weird and unexpected. Like all the other stuff there should be some fairly self-evident connection to the topic at hand, not to mention I can only milk medical stuff specifically so much before the article gets monotonous. So I browsed the 'neurological' tag until I found something that had no apparent explanation that fits the timeline and was sufficiently weird.
… that said, these issues do sorta force me to tip my hand a bit. While it's meant to stand on its own merits regardless, the early stages of brainstorming for Operation HEALTH had it as a GOI. I ultimately didn't like having a big group of fucked up germophobes appear for no reason so I wrote this SCP as an origin story, and then I couldn't think of something to give them an edge & get them together until I thought "HIVE MIND" and at that point I couldn't properly call it a GOI any more than Directorate K is a GOI. But I still wanted this to be viable as a springboard for future writing of myself and others — a GOI in all but name. Not like I haven't made my mark on that list already, lol.
So, that underpins a lot of the crosslinking and redaction. The former because I wanted to make it as clear as possible that 3404-C knows about and has a stake in the anomalous world and is properly embedded in the Foundationverse; the latter because I wanted to make it clear that the whole story of SCP-3404 is not contained in this document, and that there's room for other pieces (or other authors) to work.
The redactions are also supposed to serve as speculation fuel — given what we know about 3404-C, and what we know of what it does, what else could it be doing that the reader isn't supposed to know? A lot of the event log was based around that — stuff that serves to leave people intrigued without providing too many answers, mixed in with stuff whose purpose is perfectly obvious.
I can understand how the redactions and crosslinks could potentially be offputting, but I judged they were necessary to evoke the feelings I wanted and situate the article where I wanted it. I'm open to more thematically appropriate suggestions to put over 2315 (following the criteria in the first paragraph), but I do prefer that they continue to be Very Weird.
